JOHN F. SEIBERLING, OF AKRON, OHIO.

TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent N0. 470,214, dated March 8,1892.

Application iiled July 2, 1888. Serial No. 278,766. (No model.) I

T @ZZ whom it may concern:

Be it known that I, J o HN F. SEIBERLING, of

l Akron, county of Summit, and State of Ohio,

ksheet of paper or other material.

My invention relates more particularly to' the construction andarrangement of the machine-frame and type-levers; to the means forcovering the inking ribbon or pad when not in use and thereby protectingthe same from injury resulting from the action of the air thereon,evaporation of the ink, accu mulaton of dust and dirt, or other causes;also, to the means for locking the type-levers or their actuatingmechanism while the ink ribbon or 'forms the ink-pad holder.

pad is covered, and in certain other features of construction andarrangementhereinafter set forth.

In the accompanying drawings, Figure l represents a section from frontto rear of a type-writing machine embodying myimprovements. Fig. la isan enlarged sectional View showing the manner of adjusting the inkingdevice. Fig. 2 is a side elevation of the inkpad holder. Fig. 3 is aplan View of the parts shown in Fig. l. Fig. 4e is a sectional viewsimilar to Fig. l, showing a modified .form of type-actuating mechanismand means for covering the ink-pad; and Fig. 5 is a plan view of thesame.

Arepresenls the base of a type-writing machine, upon which all the otherparts are mounted.

B B indicate the uprights or standards, upon which a ring or annularframe O is secured by screws or in any usual manner.

D represents an annular piece or ring which Said ring surrounds, snugly,the annular frame C, and is adjustably connected therewith by means ofscrews c, passing through inclined slots d, Fig. 2. The pad-holder is ofannular form in cross-section, or, more accurately speaking, has twovertical portions D and D2 connected by a horizontal portion of flangeD, as best illustrated in Fig. 1n, thus forming a receptacle for aninking-pad E. The latter is annular in form, is composed of any materialadapted to the purpose of receiving and holding ink, and when inposition for use occupies a place just above the plane of the annularframe O, forapurpose that will appear. vWhen the type-writer is not inuse, the pad-holder is lowered by rotating the same partially aroundthe. frame O, when the inclined grooves act upon the pins or screws c,the effect being to depress the pad-holder and cause the inking'- pad totake up a position in horizontal line with said frame O, as shown indotted lines, Figs. l and l, against which it rests in close contact orproximity, the object being apparent- Viz., to protectsaid inking-padfrom injury of any kind, whether from dust, dirt, evaporation of theink, or other cause. Another object in adjusting the ink-pad is to bringa new surface thereof into position for the types to get their supply ofink from and also to prevent too much wear in one spot,'caused by saidtypes striking and resting continuallyin one place on the ink-pad. Knobsd may be employed for enabling the operator to adjust the pad-holder.

For the purpose of securing the inking-pad in place, and for theadditional purpose of protecting the types and type-levers from injurywhen the machine is not in use,a ring or cappiece F is slipped over thepad-holder D, as shown, being secured by fitting tightly or snuglyaround the portion D2 of theA padholder D, or it may be secured in anyusual or preferred manner. The cap-piece F is also angular incross-section, its horizontal portion overlying the inking-pad and itsupper vertical portion being in the same vertical plane with the innerface of the inking-pad. Vhen the pad-holder is lowered, as describedabove, the inner portion of the cap F will occupy the position latelyoccupied by the inking-pad,as shown in dotted lines in Fig. la. ing-padwhen in use is located in such position that the types will rest againstit, accordingly when the pad-holder is lowered the upper portion of thecap F will occupy a similar relation to the types and prevent injury tothe same.

G represents a central standard or post, and

As the inky IOO G an upright or support adjustable vertically in asocket in said standard,being secured at the desired adjustment by ascrew g. Said support G is provided at its upper end with a hub andradiating arms g2, which uphold a ring H, preferably rectangular incross-sec tion, as shown inl Fig. l. Upon this ring a number of guide-plates I are secured by means ot foot flanges and screws, as shown, orin other suitable manner. Said guide-plates I are each provided with aguide-slot I and vertical guide wall or projection tor a purpose thatwill hereinafter appear.

.I .l indicate the type-levers or levers which carry the types used inmaking the impressions. At their upper or type ends these les vers areby preference made solid; but at or near their center they arebifurcated ort'ormed each with two similar parallel arms, which embracethe ends of links or arms K. The latter extend from said connectionoutward to beyond the annular frame C, where they are pivoted to lugs ofan annular frame I., sur rounding the standards l and attached theretoby means of brackets M, as shown. rlhe type-levers are also providedeach with a pin or rollerj, which is adapted to travel in the slot I otthe guide-plate I and against the vertical projection 'i of saidguide-plate for assisting in the proper guidance of the typelever in itsmovements. 3y this arrangement it will be seen that the type-levers haveno fixed pivots, but that such pivots change or move in guide-slots andconstitute whatI term iioating type-levers. Supplelnental arms K arealso employed, pivoted at their outer ends to lugs of frame L andextending inwardly in a plane substantially parallel with arms K,referred to. rlhe inner ends of these levers form stops, against whichprojectionsjzof the type-levers .I strike and rest, when operated ashereinatter described, for limiting the movement of the type-lever anddirecting its course in a vertical line, so that the type may strikesquarely against the paper and produce a clean sharp impression. Thearms K and K are connected by links 7c. Pendent links or rods N connectthe arms K with a series of key-levers O of diiterent lengths, eachsuitable as to length to the location of the 'link or rod with which itis connected, and

said key-levers are pivoted at suitable points in the tulcrum-posts P onthe base A of the machine. The levers O all extend toward the front ofthe machine, as shown in Figs. l and 4, (left hand), where they areprovided with upwardly-extending rods R, to which the operating-keys Sof the type-writer are secured.

T indicates an inclined table, which is provided with perforations,through which the rods R pass-and are steadied in their movements, thetable being secured by its connection with the outer ring L at its upperend and with a vertical plate or support T at its lower end.

U represents the platen or roller which carries the paper to receive theimpressions of the types.

In Fig. l the typelevers are shown in both the operative and inoperativepositions, with the operating devices and links in correspondingpositions. Vheu a key is depressed, the rod R depresses the end of thelever O, to which it is connected. The opposite end of said lever isthus elevated and operates through the medium of link or rod Nte rockthe arm II upward on its pivot. The inner end of arm K is thus caused toact upon and throw up the type-lever J until the type ,y thereon strikesthe paper and produces an impression. The key being released, a suitablespring O elevates the outer end of lever O, thus returning thetype-lever and its connections to their position of. rest, the types jlying against or in contact with the inkingpad E, as shown.

A modified form of guide-plate I is shown in Fig. Lfl, in which saidplateis provided with an L-shaped slot I. Said slot is inclosed, asshown,which enables me to dispense withthe supplemental arm II', as thepin .7", not being able to escape from the slotI, the latter acts inplace of arm K to limit the movement of the type-lever and guide thesame in a vertical path. Now when the type-writer is not in use theink-pad holder is adjusted to its lower position, as above described, oruntil the ink-pad E occupies the position shown in dotted lines in Fig.l, The cap F is thus brought down and protects the types from injury. 3ythe adjustment of the pad-holder to such position the lower edge or facedi thereof will descend to the position indicated in dotted lines inFigs. l and l, which will prevent the arms K from rising, thus lockingthe type-actuating mechanism in the position of rest. It will thus beseen that by the adjustment of the ink-pad holder the ink-pad and typeare covered and protected and the type-actuating mechanism locked orheld inoperative until the pad-holder is moved back to its formerposition. y

In Figs. 4 and 5 a modified form of devices for covering the inking-padis illustrated. The movable pad-holder in this case is dispensed withand the annular frame C is recessed or cut out to receive the annularinking-pad E. rlhe inking-pad being thus stationary, the upper verticalportion of the cap F is also dispensed with. The outer ring I. may alsobe dispensed with and the arms K pivoted directly to the annular frameC, as shown in Fig. 4.

The device for covering the inking-pad is composed of an annular plateor cylinder V, extending around within the annular frame C and fittingsnugly against the ink-pad E, as shown. Said covering-plate V isprovided with slots n, through which are inserted pins or screws c',thus allowing said plate to be adjusted up and down for covering oruncoverin g the in kin g-pad. llo provide mechanism TOO IIO

for adjusting said plate V, links w are employed, attached at one end tosaid plate and operated at the other end by crank-arms w on rock-shaftsW.

X indicates a bar or plate, which extends transversely across and nearthe front ot the machine and underlies the key-levers O, as shown inFig. 4. Said bar connects the crankshafts WV through the cranksa: 0c, sothat when one shaft W is operated bya handle or crank Y for that purposethe other shaft W' will also be caused to operate for simultaneouslyoperating the links w and adjusting the plate V. The cranks w anda: areso arranged that when the plateVis elevated to cover the inkpad the baror plate Xwill also be raised to a position directly beneath thekey-levers O, thus locking the type-actuating mechanism in the positionof rest simultaneously with the covering of the ink-pad, both ofwhichresults are accomplished by only one act on the part of theoperator-viz., operating crank Y.

Having thus described my invention, what I claim as new, and desire tosecu re by Letters Patent, is-
